1999 Chevy Cavalier radiator fan

did you chec the fuse to see if it was good

Yes I have replaced the 30 amp fuse and each time it will burn out.

disconnect the fan and see if the fuse will burn out then

If 30 amp fuse does not burn out with fan disconnected, what maybe the problem?

most likey the fan motor. you would need to check resistance in the fan motor.

what resistance should I read if the motor is defective or good ?

it will be a very low reading if it is bad. what kind of reading are you getting

Since your last reply, I have determined that the fan is defective. I have been able to release the fan assembly, but unable to remove it due to the upper left frame portion being in a track on the radiator and very tight space to work with. Is there a special method to use in removing this part ?

Also, there is no power to the high beam lights. I have determined this with the high beam switch on and the use of a 12volt meter. I have been told that there may be a broken wire in the wiring harness near the battery. Are you aware of this type problem with this type car, also the same for the pontiac sunfire, and were is the most likely spot to find it near the battery ?

ive seen them more in the front across the bumper. but that was mainly day time running lights. did you check to see if there was power coming out of the dimmer switch when the high beams are turned on

Yes there is power to lights with dimer switch on high beam. To get the high beams working I had to bridge the LHS pink to the RHS pink, the dark blue was already bridged from LHS to RHS on a previous repair. After doing all this I still have no day time running lights. I have replaced the Relay and still no DRL. Any further suggestions for a possible fix.

is the power to the high beams constant ot just when you are pulling back on the switch

It's constant.

do you have the wiring back to factory. if you dont put it back to factory and we will start from scratch
